Very helpful. Also, very frustrating. I thought the thing about SIM cars was that they were universal?

Could you add the S8 Active?

I'll make a spreadsheet for non BYOD devices in time.

Sims are sorta "universal" if you take into considering the BYOD ones. The great reason why Sprint has so many sim variants is they're developing the sim card module as they update their network and devices. They have little experience in that category so must constantly iterate in order to take advantage of new technological developments on the handset and on the network side. We can see this move from USIMs to CSIMs and now ISIMs.

I'm kind of confused as to why the new SIMs aren't backwards compatible in that case. In China, with China Telecom, it was great. They're a CDMA/LTE carrier very much like Sprint, but it was one SIM for all devices, just like a GSM carrier. Their SIM cards (UICC I assume with CSIM app and... ISIM app? USIM app? I'm not sure) were even able to be used in a Sprint LG G5 I had with me - 3G/voice was EV-DO/1xRTT and LTE on Band 3/26. What makes it so hard for Sprint to do something similar, at least with all devices that don't use NV programming?

Interesting acquisition announced today....Blackberry to acquire Good Technologies. For those of you who don't know or are familiar with Good, it's basically a BYOD platform for enterprises. (Email, intranet, etc.) Not necessarily directly Sprint related, but many people use both.

I've seen some threads recently about the differences between SIM/UICCs and though posting a compatibility matrix would help people.

This is pretty straightforward. The matrix has every Sprint LTE device, and what UICC card is meant for that device. Mix and matching UICC card types probably will not work, but swapping around UICC cards for devices that use the same type of card should work properly.

Keep in mind, you cannot simply move your UICC card to another phone to use it. Sprint's device authentication system still requires the correct UICC and MEID to be on the account to authenticate properly and work.

Resurrecting an old thread, I saw B41 LTE in Magnolia, MS on I-55 the other day. Ran a speed test and it was in the mid 30's. I was traveling south to north on the interstate and saw what appeared to be the alpha and gamma sectors. This is new to me!!
